Lithium-ion Battery Deep Cycle Performance and Cost

Lithium-ion cells serve as the technology of choice in several applications today. It has overtaken other batteries due to their power density and specific energy. The relationship between specific energy and power is vital for the performance of the device. Li-ion has deep discharge compared to batteries like lead-acid. They are all deep cycles that mean they can be fully charged and discharged. Let us see the best lithium-ion deep cycle battery and cost.

Do all lithium batteries have a deep cycle?

When manufacturers talk about renewable energy batteries, it means deep cycle batteries. The cells have energy storage units where a chemical reaction takes place then develops a voltage that results in electricity. These batteries are designed to recharge and discharge many times. Deep cycle cells give power at a normal rate for a long period.

All lithium batteries are deep cycle. They can give power for a long period until they are recharged or reach 80% discharge.  Nonetheless, the manufacturer's advice that the discharging rate should not go below 45%. If you follow the guideline, you will extend the battery life of the battery. The cells can be used for critical applications including marine, recreational, handling materials, golf carts, and renewable energy.

What is the best 12V lithium-ion deep cycle battery?

Renogy Lithium-iron-phosphate Battery

Renogy lithium-iron-phosphate cell is the top choice of lithium-ion models. The cell is available at a premium cost but it will last 10 times longer compared to a regular lead-acid deep cycle. Renogy charge fast requires zero maintenance and has less weight. It has a 12V 100Ah deep cycle and comes with an inbuilt protection battery system. This protects the battery from many cycles and makes sure its running performance is at a peak.

The cell has over-discharge and overcharges protection and short circuit protection. Also, it has an internal cell fuse. Besides that, the battery has a stainless steel cell case that serves as explosion-proof. Robust built has fire retardant additives. You will not destroy the battery even if it undergoes a 100% depth of discharge. Make use of the full capacity. It operates at a charge temperature between 32 degrees to 113 degrees and a discharge temperature of -4 degrees and 140 degrees.

The lithium-ion cell is compatible with a wide range of smart chargers and controllers. This is because of the compact build and lightweight that creates a large building power bank with many cells in parallel. Moreover, it is a great substitute for gel, AGM, and old flooded batteries. Go for energy lithium-ion if you have extra money, it is the best deep cycle lithium battery. It is better to invest in something that will give a high-quality performance.

Other Best 12V Lithium-ion Deep Cycle Battery to Consider

BattleBorn 12V Lithium-ion Battery

This is a great alternative for energy batteries. It has a battery management system and has amazing features which help to achieve 5000 cycles.

Torque Power 12v Lithium Deep Cycle

Great replacement if your budget cannot buy a $900 battery. Expect 2000 cycles and you should discharge to 20% consistently.

AIMS 100 Amp 12v lithium battery

Just like other lithium batteries, AIMS has an online battery management system, and manufacturers claim that it reaches 4,000 cycles. However, you can be sure to achieve 3,000 cycles. Regardless, AIMS offers safety precautions by including fused cells which isolate in case of damage. For this reason, it prevents the components of the cell from overheating.

Is 12V lithium-ion deep cycle battery worth the cost?

Lithium batteries are among the most expensive cells in the market today. They cost 5 times more than lead-acid batteries. However, it provides high power to several lights, appliances, and other electronics. Why should you spend money on lithium-ion deep cycle battery? It is an investment and here are top-level views of 12V lithium-ion:

More Energy Density

Low Temperature High Energy Density Rugged Laptop Polymer Battery Battery specification: 11.1V 7800mAh -40℃ 0.2C discharge capacity ≥80% Dustproof, resistance to dropping, anti - corrosion, anti - electromagnetic interference

The batteries have a specific energy level of 150Wh/kg unlike general AGM has 30-40Wh/kg.

Lightweight

12V lithium-ion deep cycle cell weights 26lbs. on the other hand, the lead-acid deep cycle cell weighs 60lbs. you have to consider something that is easy and manageable to work with. A lightweight battery can be transported without feeling the extra weight.

Long-lasting

Lithium-ion batteries have undergone a wide range of advancements. It can offer more than 3,000 and above cycles without creating issues. The performance does not decrease even after thousands of cycles. Normal AGM battery can only offer a maximum of 400 charge cycles.

Fast Charging

When it comes to charge, 12V lithium-ion dominates AGM cells. Charging fast is a lifesaver especially when you are not going to spend the whole day at home. 100ah 12V lithium-ion charges 3 to 4 times faster than a lead-acid battery.

Great Discharge Levels

12V lithium-ion can be drained up to 20% and it will not destroy the lifespan. Single lithium-ion will meet your demand than 2 lead-acid cells.

The best 12V lithium-ion deep cycle battery costs $800 to $1,000. This is quite expensive and it will cost you extra money than buying other brands of batteries. However, you have to consider performance and other key features first. It is better to invest in something that will meet your expectations. Lithium-ion has many positive features that every battery user desires. Normal AGM comes at $200 but it does not last for long. Lithium-ion will offer 6 times life cycles than AGM. If you look clearly, the cost you will spend on buying several AGM will be more than investing once on lithium.

Final Thoughts

Lithium-ion batteries are a great choice for powering systems. This is because the cells can be charged without maintenance. Nonetheless, maintaining your cell and flowing safety guidelines will increase the life cycle. They are the best when it comes to tolerating the level of discharge. The cells can safely undergo 100% depth of discharge and still maintain 98% efficiency. Most lithium with deep cycles has 10,000 life cycles at 80% depth of discharge. Also, the deep cycle lithium is easy to work with and is lighter than other cells. They can weigh between 7.35 kg to 14.8kg depending on voltage and amp-hours.
